ABSTRACT:
A conductive member has a first face adapted to be mounted on a board on which an inspection circuit is arranged and a second face adapted to be opposed to a device to be inspected. The conductive member is formed with a plurality of first through holes having a first common diameter and communicating the first face with the second face. A first contact probe is provided with a first tubular body having a second diameter which is smaller than the first diameter, and a first plunger retractably projected from one end of the first tubular body. A second contact probe is provided with a second tubular body having a third diameter which is smaller than the second diameter, and a second plunger retractably projected from one end of the second tubular body. A retainer is formed with a plurality of second through holes having a common shape, and provided on at least the second face of the conductive member so as to communicate the first through holes with the second through holes, so that the first contact probe and the second contact probe are retained in the conductive member while only the first plunger and the second plunger are projected from one ends of the second through holes.
